[origin: US6099955A] PCT No. PCT/JP97/00632 Sec. 371 Date Sep. 3, 1998 Sec. 102(e) Date Sep. 3, 1998 PCT Filed Feb. 28, 1997 PCT Pub. No. WO97/32923 PCT Pub. Date Sep. 12, 1997A urethane foam for shoe soles prepared by reacting a compound having at least two isocyanate-reactive hydrogen atoms and a molecular weight of 400 to 10000 with a polyisocyanate in the presence of a foam stabilizer, water and a catalyst, characterized in that the ratio r1/r2 of a mean skill cell diameter r1 to a mean core cell diameter r2 is 0.02 to 0.80, wherein the mean skin cell diameter r1 is defined as the mean diameter of the cells which form the skin portion of a urethane foam extending from the surface to a depth of 5% of the foam thickness and the mean core cell diameter r2 is defined as the mean diameter of the cells which form the core portion of a urethane foam extending from a depth of 40% to a depth of 60% of the foam thickness.
